BUTTON-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,134, dated August 9, 1887. Application filed June 9, 1887. Serial No. 240,715. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM OLIvER GRAIN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Button-Attaching Machines, of which the following is a specification.

This invention relates to a machine for attaching metal buttons to garments, and isillustrated in the accompanying drawings, (three sheets,') in which- Figure 1 is a side elevation of the machine, showing thepnnch raised. Fig. 2 is an elevation showing a side view of certain portions and a vertical section of other portions. In this view the punch is lowered. Fig. 3 is an elevation showing a view of the side opposite oi-reverse to that seen in Fig. 1. Fig. 4 is a top view of the button hopper or turret and slidcway. Fig. 5 is a section (larger scale)of the slidcway for the buttons. Figs. 6 and 7 show side and bottom views of the turret-hopper. Fig. Sis a section of the base on which the turret revolves, and shows also a part of the slidcway. Fig. 9 is a view of the arm by which the turret is revolved. Figs. 10 andll are sections of the same device seen in Fig. 9, each showing a different construction. Fig. 12 is a view of the punch and follower. Fig. 13 is asectional view of a button.

The letter A designates the frame,which has two slide-bearings, b I), for the punch O and follower D. These bearings are one above the other in an inclined axial line. This position is part of a contrivance to effect an end hereinafter mentioned. The punch O is raised and lowered by a lever, E, which is pivoted in a bearing, 0, at the topof the frame, and a link, (1, connects the punch and lever. By depressing the free end 0 of the lever the punch will be raised, and by elevating the said free end 0 the punch will be lowered. The follower D is raised and lowered by a lever, F, which is pivoted byabolt, 6, near the lower partof the frame. This lever F is actuated by mechanism which is connected with the punch-moving lever E. A spring, f, is fixed to the frame A and bears on the lower side of the leverF near its end and thereby presses said end up, which results in lowering the follower D. A rockshaft, G, in the frame has a cam, G, on it. .Vhen the flat sidef of the cam is in contact with the top of thelever F the follower D will be lowered, as in Fig. 1; but when the round part of the cam is in contact with the lever F,

as in Fig. 2, the follower will be raised.

The cam-lever F is provided with an illclined bearing-platc, g, which is movable along the lever and serves as an adjustment for the movement of the follower. This plate has a the punch lever E is the arm 1', which is attached to the rock-shaft G, and the link which unites this arm with the punclrlever E. It will thus be seen that whenever the punchlever E is moved the rock-shaft cam G will also be moved. The result is that thepunch O and follower D are both moved and that their movement is properly timed.

The follower D has at its upper end a point anvil, k. The button Z passes from the turret down the slidcway II to theseatl below which is the said point-anvil, by which the button is centered for the action of the punch C. The button has a concave center, k, which has position below, and the end of an eyelet, m, which is to be upset, points upward. vil It takes in the concave center L of the button, and by lifting the latter slightly causes it to be centered. The punch G has at itslower end a point, m, which comes down into the upturned end of the eyelet, and the latter is there upon upset.

The buttons Z are placed into the turret shaped hopper l, which resembles an inverted cup, and is mounted on shaft 1, having hearing in a plate, J, attached to the slidcway H.

The plate J forms the bottom of the hopper, and the latter revolves in an inclined plane within a circular rim, J, on said plate. The turret-hopper has a central hub, a, and a setscrew, n, in the hub secures it fast to theshaft 00 I. A hole, if, in the wall of the turret opposite the set-screw serves for a screw-driver to have access thereto. The lower edge of the turret has slit-openings Z, for the escape or discharge of the buttons one at a time into the slidcway H. Its wall is also provided on the The 65 The poi.nt-an- 85 i on the neck.

interior (see Figs. 2 and 7) with radial proectmg pins 0, which, asthe turret revolves, serve to carry the buttons to the dischargeopemng Z in the circular rim J, and also serve to stir the buttons and place them in position where they will be certain to discharge.

The circular rim J, which surrounds the hopper, has an undercut groove, g, which is eccentric to the shaft I. This groove is shown n Flg. 2 and is indicated in Fig. 8. The Ohect of this groove is to receive the rim of the buttons, and thereby insure that the buttons wlll take the proper position to be discharged through the opening Z.

The inclined slideway H is formed by two parallel guide-strips, r, secured on a plate, 3. The confronting edges of the guide-strips are undercut, as shown at r, and form a groove for the buttons, which slide down on the plate 3 between the guide-strips. The upper end of this groove coincides with the opening Z in the rim J, through which the button discharges. The slideway H inclines down to the seat Z", and if a vertical line be drawn through said seat the slideway will be seen to be inclined at one side of said line and the punch C and follower D reversely inclined at the other side of said line.

The turret-hopper I has an intermittent revolvlng motion, which may be imparted to it by any suitable or known mechanism. In the present instance an arm, L, is on the shaft 1, and a rod, t, connects the arm with the punchlever E. This arm L may be attached on the shaft 1 by a pawl and ratchet "or similar de- V/lGG. A collar, 10, is fitted tight on the shaft I and has a neck, it, around which the ring L of the arm fits and turns loosely. The armrlng L has a slot, 1), (see Figs. 9, 10, and 11,) which extends in a tangential direction with respect to the circumference of the neck a, and a loose p n, w, occupies the said slot. pin u IS in the slot end closest to the neck a, the pin will bind against the circumference of said neck, and'thereby the arm will be made fast to the neck; but when the pin 10 is in the slot end farthest away from the neck it will not bind, and the arm L will be free or loose The arm L is thrown back and forward by the action of the rod tand lever E. When thrown one way, the arm causes the shaft 1 and turret to move; but when it is thrown.

the other way the ring L of arm will turnfreely on the neck u, and neither theshaft nor the turret will move.

The collar u may be made fast to the shaft I by a set-screwmc, so that it will not slip, as shown in Fig. 10, or the collar may be made fast enough to insure it to turn the turret I under ordinary conditions, but so it will slip on the shaft I in case the buttons should by any chance choke the turret and prevent it from moving. An example of this latter mode of fastening the collar is shown in Fig. 11. The

shaft has a groove, y, around it, a metal plug, 2, 1n the collar fits in the said groove, a piece When the of leather, 2', rests on the metal plug, and a set-screw, w, presses the leather. This arrangement prevents the set-serewifrom binding rigidly on the shaft, and the result is that should the turret become choked the collar will slip around the shaft.

A button-stop to arrest the button moving down the slideway when it reaches theseat 1 comprises an angular arm, N, pivoted at e. The point end (1 of the arm is at the lower end of the slideway and stops the button. spring, 1?, bears on the rear end of this pivoted arm and keeps the said point end normally across the lower end of. the slideway. When it is desired to detach or draw out abutton from the slideway, a slight pull will cause the arm to yield sufficient to allow the button to pass.

The herein-described construction and position of parts insures that thebuttons willmove down the slideway H, which inclines at one side of the seat I, by their own gravity, and as the punch Oand follower D have an axial line,

which is reversely inclined at the opposite side of the seat, the latter may be square or at right angles with respect to said punch and follower without having an objectionablebend or angle at the point a in front of the seat.

Having described my invention, Iclaim and desire to secure by Letters Patent of the United Statesi 1. Ina button-attaching machine, the combination of the punch O, the follower D, the lever F, connected with the follower, a spring bearing on the lever, and a cam, G, also acting on the said lever.

2. In a button-attaching machine, the combination of the punch G, the follower D, the lever F, connected with the follower, an adjustable inclined bearing-plate, g, on the said lever, and a cam, G, for the purpose set forth.

3. In a button-attaching machine, the com bination of the punch O, a lever, E, for actuating the punch, a follower, D, and a lever, F, connected with it, a cam, G, for actuating the follower-lever, and mechanism, substantially as described, connecting the saidcam 4 with the punch-lever.

4. In a button-attaching machine, the combination of the punch O, a button-seat, Z, an inclined slideway leading to the button-seat, an inclined plate at the upper end of the slideway having a circular rim, J, provided with an undercut groove,q, eccentric with respect to the shaft in the center of the plate, and an outlet-opening, Z, and a bottomless turret-hopper, I

I, revolving within the said circular rim and provided with pins 0, attached to the interior wall, for the purpose set forth.

In testimony whereof I affix my signature in the presence of two witnesses.

WILLIAM o. GRAIN.
